SCREEN FASTENING FOR CAR WINDOJVS.

Application filed August 23, 1923.

To all whom it may concern:

Be it known that 1, WILLIAM O. Srirrii, a citizen of the United States, and resident of Chicago, county of Cook, and State of Illinois,have invented certain new and us ful Improvements in Screen Fastenings for Oar lVindows, ofwhichthe following is a specification, and which are illustrated in the accompanying drawings, forming a part thereof.

This invention relates to railway cars and more particularly to the screens and screen construction for the windows of the side walls of the car.

One of the objects of the invention is the provision of a screen frame that may be easily and readily placed in position and removed therefrom without disturbing the means for supporting the same.

Other objects of the invention are the provision of a screen frame and supporting means with cooperating attaching members associated therewith that are simple in construction, efficient in operation and not likely to become broken or get out of order.

Other and further objects and advantages of the invention will appear from the following description talzen in connection with the accompanying drawings, in which Fig. 1 is a vertical section of a portion of a side wall of a passenger car showing the invention in position therein, with parts omitted and parts broken away;

Fig. 2 is a perspective view of supporting frame;

Fig. 3 is a perspective view of the screen frame, with the screen wire in posltron therein; and

Fig. 4 is a side elevation of a portion of .the screen frame on an enlarged scale, with parts in section and parts broken away.

On the drawings the reference character 10 designates the side of a railway car having a window sashll therein. The window sash 11 is provided with one or more glass panels 12 and the lower portion of the sash is rabloeted as at 13 and again at 1-1 to form a stepped recess as clearly shown in Fig. l of the drawings. The outer downwardly extending portion 15 of the window sash formed by the stepped recess is adapted to engage the outer window sill 16 and is supported thereby when the window is in loweredpositioii. a

The sill. 15 is provided with an upwardly the window Serial No. 658,951.

raising and lowering of the window sash.

hen the window is in elevated position the screen will occupy the space between the lower portion of the window sash and the lower portion of the window frame or casing thus preventing the entrance of cinders and the like into the car, as is constructions.

Since the screen raising and lowering mechanism constitutes no part of the present invention it is not thought necessary to show and describe the same.

The screen 19 comprises a window sup porting frame 20 and a screen frame 22 ,detachably secured thereto whereby the screen frame may be removed if desired without removing the supporting frame. The supporting frame 20 may be arranged in any suitable form as in the form of a rectangle as shown in Fig. 2. This frame is provided with stops against which the screen frame 22 engages when the parts are assembled. As shown, the frame 20 is formed from angle iron arranged in the usual in such form of a rectangle with one of the flanges 20 extendmg inwardly 1n the plane of the frame to form a stop. The lower portion of the frame 20 has an extension 21 which is provided with an angular slot 21, which cooperates with a suitable holding and operating means, not shown.

It is sometimes a convenience to be able to remove the screen frame without removing the supporting frame. In other words, it is desirable that the frames be so constructed thatthey may be readily separated. The followin mechanism is provided where by this may be accomplished. The screen frame 22 is so constructed that it will fit *ithin the supporting frame 20 and means are provided whereby the parts when properly assembled are automatically locked in position. The frames are provided with interlocking connections at one side thereof and with a detachable locking connection snare lOU Lit)
